• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((y lang) OR (_ lang)) ha hoi. thien van lam thuoc va ((danh vi) or (dinh vi)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y lang) OR (_ lang)) ha hoi. thien van lam thuoc va ((danh vi) OR (dinh vi)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y lang) OR (_ lang)) ha hoi. thien van lam thuoc va ((danh vi) or (dinh vi)) cuu tre".
